FEEDING MECHNISM FOR CARDlNG-NIACHINES.

SPECIFICATION forming part oflLetters'Patent NO. 650,221, dated May 22, 1900.`

Applicatin filed September 12,189@ Serial No. 730,205.' (No model.)

.To all whom, t may concern: i

Beit known that I, EDDO V. BATES, a citizen of the United States, residing atDracut, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Feeding Mechanism for Carding-Machines, of which the following is a specification.

This invention is an improvement on feeding mechanisms of the class described and illustrated in Letters Patent of the United States granted February 19, 1895, and numbered 534,418; and it consists in the novel construction and arrangement of parts described, and illustrated in the accompanying drawings, whereby the spring described in the said Letters Patent is done away with 4and a weight and lever employed and utilized with the effect of producing a uniformity of tension on all sizes of sliver impossible in practical operation when a spring is employed, preventing pinching the sliver, and thus obviating danger of kinking, and the edge of the stock is prevented from catching on one of the feed-rolls.

` In the accompanying drawings, in which similar letters of reference indicate corresponding parts, Figure l represents a front elevation of a feeding mechanism illustrating the invention. Fig. 2 is a vertical section taken on line 2, Fig. 1. Fig. 3 is a vertical section taken on line 3, Fig. 2. Fig. 4 is a horizontal section taken on line 4, Fig. 3.

Similar letters of reference indicate corresponding parts.

The distributing carriage comprises the vertical plate or web Aand the rearwardlyextending horizontal shelves A' A" integral therewith, said carriage being guided `and supported by the shaft B, which has a sliding iit in a pair of brackets A", bolted to the web A of the carriage and surrounding said guide-shaft B. The carriage is furthermore provided with a vertically-slotted upright bar C, whose foot C' is bolted at C" to the bracket A", such slot being engaged by the chain D by means of a pin d, as in the Letters Patent above referred to.

E is a vertical shaft -journaled in the vertical post or bracket e integral with the shelves A' A", carrying at its lower end` the feed-roll F and rotated bythe gear-wheel `F' on its up- 'per end, the beveled surface E" of said gearwheel being engaged by the driving bevelgear f on the shaft B in the usual manner.

H is a vertical Vshaft j ournaled in a bracket sliding in tracks or ways L L', formed on the upper surface of the shelf A' and the under side of the shelf A" and being parallel with the web A. The lower end of this shaft II carries the plain feed-roll N, and the shaft is carried by a gear-wheel H', fast on 4its upper end and engaged by the gear E', the teeth in these two gears being long enough to make engagement without regard to the horizontal sliding of the shaft H and bracket K.

P P' represent a bent lever whose portion P' extends horizontally through and has its bearings in a horizontal extension a, integral with the carriage, and also through a collar S, into which it is secured by a set-screw b. This collar is provided with a wing S', from which a lug S" extends and bears normally against a projection K", extending rearward from the outer end of the part K'. A weight R is adjustably placed on the part P of the lever. This lug S" holds the sliding base K' normally in and the gear H' in closest engagement with the gear E' by means of the weighted lever P P', and also acts as a stop when the lever is swung up, preventing the sliding base from disengagement therewith and the gear-wheels from becoming disengaged from each other. Guide-rolls T bear against the rail U.

When the sliver is conducted between the rolls F N by the guide V, the roll N is pressed back horizontally against the power of the weight R, the base K' sliding in the ways L L', pushed by the lug S". .The weight is adjusted on the lever with relation to the size of the sliver. Thus the tension or pressure on the sliver is practically uniform and kinking is prevented.

When the feed-rolls, or either of them, are formed with ordinary spur-gear, the stock is very liable to catch on the edge of the rolls. In this improvement I preferably make one roll plain, and the roll F has plain peripheral edges, while centrally on its surface on lines with its axis are parallel elliptical depressions F', whose ends are at appreciable distances from the edges of the wheel. This leaves the IOO - edges of the wheel perfectly smooth and "at the same time provides means forengaging. and feeding in the sliver Without catching and holding it. Y p 0 l Having thus fully described my invention, what I claim, anddesire to secure by .Letters i Patent, isf 1. ln a feeding mechanism for carding-machines, a traveling distributingkcarriager a feed-roll mounted'on a shaft having bearings in a stationary bracket supported by the carf' riage; a bracket adapted to slide horizontallyj with relation to the iirstjnamedblacketba feed-roll mounted on a shaft having bearings: vin the said sliding bracket, whereby the fee'd'" l roll'mounted therein is adapted to move horil' zontally tovyard` and from the firstnamed feedroll-as the 'sliver passes between the rolls ;`v an'df a Weighted lever pivotedjto .the carriagean'd engaging with the said *sliding bracket'and thereby holding the feed-roll sus` tained by said bracket normally against the feed-rollsustained bythe stationary bracket, substantiallyasset forth..

2. vIn a feeding mechanism for carding-1na chines, Va traveling distributing-carriage; a

bracket; a Weighted lever pivoted to the cargriageya projection extending from the inner 13.131911?v Saidhorizontal extension; a lug extending from the inner end of the lever and 'f'gaging with said projection; and mechanism for actuating the shaftrupon which the feed-rolls are mounted, substantially as4 andv for the purpose specified. i
